Small leak, but I don't like any leaks on my cars. I like to take care of them right away. My tech seems to think it's a timing chain cover. Says he does them all the time on the 202. He says no big deal. I'm bringing it by this Thursday, and see if he's right. I felt around but couldn't seem to see exactly where it was coming from. Very light film of oil on the left side of engine block. Generator is not covered in oil, or air pump. Oil isn't milky and I'm going to look at the coolant today. Thank you for your input.
